Rigidly mounted in each end of these blocks are dowel or guide pins 29 and 30 the free ends of which are loosely positioned within apertures 31 and 32 in said cross bar24'of the chase :6. Blocks 27 and 28 are rigidly secured uponthe outer ends of the "stems 33 and-34 of the plungers 35 and 36. Plungers 35and, '36 are slidably mounted in recesses 37 and. 38 in the lower ends of thesidemeinbers of the chase 6. At the inner'terminations of the recesses 37 and 38 are provided vertically extending screwthreaded holes 39and 40 and in these holes are mounted the set screws 41 and 42. The points of screws 41"and' 42 are tapered and bear against the beveled ends 43 and 44 of the plungers 35 and 36 so that .as saidscrews are screwed downwardly the taperedpoints thereof bearqagainst the beveled end er said plunger and'force thesaine outwardly together with the stems and the blocks 27 and 28. A collar 45 is pressed with in the outer ends of the recesses 37 and 38 and surrounds the stems 33 and *3'4-and coiled around said stems between said collars and the plungers 35 and 36'are coilsprings 46 ently of the others or any combination there and 47 which act to hold said plungers in 2 their innermost positions against the points of the set screws; I

In the operation of our invention the chase is first positioned upon the bed of the press in the usual manner with the adjusting de{ vices all in their closed positions as shown in Fig. 1. Should it be desired to raise the chase the set screws4l and 42 will be rotated, 'by'means of a suitable key or'screw driver,

downwardly when the tapered points will propel the plungers 35 and 36 outwardly and with them the blocks 27'and '28.; Blocks 27 and'28 will bear against the abutments 9-and 10 which are rigid with the bed of thepress' and the chase will [thus befor'ce'd upwardly.

Bv un'screwin the set screws the s rin s46 and 47- will be permitted to retract the plungersand blocks. Should it bedesired' 'to move thech'ase sidewise' in either direction the set screw 15, 16 on theqside of the chase.

opposite to the direction in which it is desired to move the chase will be screwed do-wnwardly thus forcing out the respeetive'steni "1 9, which will Contact with the inner-edge offthe rolle'r'track and thus move the chase in'the direction desired. Anyoneofthe-ad justing devices may be operated independof may be used.

j I From the foregoing itwill' be obvious that the chase may beeasily and quickly adjusted in any direction and at anv angle within its-- 4 limits andsecurely"locked tothe bed o'fthe claim and press when so adjusted. v

Having described ourinventionwhat we desire to secure'by Letters'Patent 1s:

means to move said plungers and blocks outwardly.
